MOTOR-VEHICLE.

1,384,283. Specification of Letters Patent.

Application filed August 30, 1916. Serial No. To all whom it may concern:

Be it known that I, Jnssn G. VINCENT, a citizen of the United States, and resident of Detroit, Wayne count State of Michi an, have invented certain new and useful mprovements in Motor-Vehicles, of WhlOh. the folll rflwing is a specification. and particularly to the motor control mechanism thereof.

Motor vehicles of the commercial type are usually provided with some sort of governor mechanism whereby the speed of the vehicle may be controlled to some extent. In such vehicles also it is customary to arrange a change speed mechanism between the motor and the driving wheels, and when the governor is driven by the motor to control the motor speed and thereby to control the vehicle speed, the lower gears of the change speed gearin are not as useful as they would be if t e overnor were operated by a moving part 0? the vehicle so that its action depended upon the speed of the vehicle rather than upon the speed of the motor. In some cases the governors have been connected so that their action depends upon the s eed of the vehicle, but as this requires that t e governor shall be mounted rearwardly of the driving shaft of the gear mechanism some difficulty has heretofore been experienced in providing suitable connections from the governor to the motor throttle.

One of the objects of the present invention is to provide a simple and efiicient connection between a governor and a motor throttle.

Another object of the invention is to provide a non-circulating fluid connection between a governor and a motor throttle.

Another object of the invention is to provide a governor connection to one of the sliding gears of a change speed mechanism of a motor vehicle.

Other objects of the invention will appear from the following description taken inconnection with the drawings which form a part of this specification, and in which:

Figure 1 is a plan view of part of a motor vehicle showing particularly parts of the motor and change speed gear mechanism and the connections between the governor and the motor throttle and Fig. 2 is an enlarged detail sectional view is invention relates to motor Vehicles -d of the control connection to m throttle. 8 motor Referring to the drawings, 10 represents a motor vehicle frame upon which is mounted a motor 11, preferably of the hydrocarbon type, and a change speed gear box 12. It will be understood that the-re is a suitable riving connection between the motor 11 and the gearing 12, usually in the form of a friction clutch which is not shown in the drawlllgS. The motor 11 is provided with a suitable 1ntake pipe 13 valve 14, shown as in the form of a butterfly valve. This valve may be operated by an arm 15 shown both in Fi 1 and 2. It Wlll be understood that the throttle valve controls the supply of combustible mixture passing to the motor and thereby controls the speed of the motor.

The hange speed gearing 12 may be of any desired form, and as shown one ofthe gears 16 is adapted to slide on the shaft 17 10h is one of the driven shafts of the gear- It Wlll be understood that said shaft 1s constantly connected through suitable shafts and gearin with one of the vehicle driving axles, so t at whenever the vehicle is moving the shaft 17 and consequently the gear 16 are in operation, the speed of said shaft 17 and gear 16 depending entirely upon the speed of the vehicle.

In one side of the change speed gear casing is an opening 18, .and an auxillary casing 19 is fitted over the opening and secured to the gear box 12 as by bolts 20. In this casing 19 is mounted a governor 21 of the fly ball considerably wider than the gear 16 is in constant mesh with the latter said gear so that the governor 21 which is mounted within said gear 22 is always operated at the speed of the vehicle.

holds the governor in inoperative position and a sleeve 24 surrounding the spring is moved by the governor to the left in Fig. 1 as the governor balls fly outwardly by centrifugal force. A yoke 25 on an arm 26 follows the action of the sleeve 24 as shown particularly in Fig. 1.

It will be understood that the movements of the arm 26 which is controlled by the governor must be imparted to the arm 15 of the throttle valve 14 in order to have the type and a gear 22 having a face A spring 23 yieldingly governor control the speed of the motor, In the present invention this is accnmphshed by means of a non-circulating fluld connection which is positive and quick in its action and yet admits of ready application to a vehicle in which the governor and throttle may be mounted at widely separated points.

In the form shown, there is an expanslble and contractible casing 27 which ispreferably made of spun metal in the fluted form shown in Fig. 1, which casing is secured at one end to the casing 19 as shown at 28.

The opposite end of the casing 27 is free to move as the casing expands or contracts, and a rod 29 at said free end is connected as by a pin and slot connection 30 to the arm 26 above described. Thus it will seen that any movement of the arm 26 Wlll be communicated to the casing 27 through the rod 29, and the casing will therefore be comressed as the governor balls fly outwardly and it will be expanded again as the spring 23. causes the governor to assume its inoperative position. In Fig. 1 the governor is shown in inoperative position and the casing 27 is therefore expanded.

Formed as an integral part of or secured to the intake pipe 13 is a housing 31 in which the arm 15 is arranged and in which also there is an expansible and contractible casing 32 similar to the casing 27 hereinabove described. This casing 32 is also held firmly at one end as at 33 and its free or movable end is connected by a rod 34 through a pin and slot connection 35' with the arm 15 of the throttle valve 14. Thus the expansion and contraction of the casin 32 operates to close or open the throttle va-ve 14 as will clearly be seen in Fig. 2. The casing 32 is shown in fully compressed position in which the throttle valve 14 is wide open.

Connecting the casings 27 and 32 isa metal or other non-contractible and nonexpansible pipe 36. This pipe may be more or less flexible and if necessary formed with several loops to giveit greater flexibility,

, turned to so that slight relative movement between the motor and the gear box Would in no way affect the connection. 4

It will be understood that the Piping 36 forms a continuous passage between the interior of the casing 27 and the interior of the casing 32, so that when the casings and piping are filled with a suitable fluid, suclr as oil, as by the filling opening 37 shown in Fig. 2, the contraction or squeezing together 'of'the casing 27 will cause a flow of the fluid through the pipe 36 to the case ing 32 and the latter wil be expanded, in direct pro ortion as the casing 27 is compressed. likewiseif the casing 27 is reits expanded condition the liquid in the pipe 36 will return, and in turn contract the casing 32. In this manner the hydrocarbon motor,

tional area between the casings 27 and 32 and pipe 36 this connection between the governor and throttle valve acts as a dash pot to steady the action of the governor and its effect on the motor.

But one form of the invention is shown, but it will be understood that other forms and changes and alterations may be made within the scope of the claims without departing from the invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. In a motor vehicle, in combination, a. hydrocarbon motor havin a gear box having a sli ing gear therein, a gear having a relatively long face in constant mesh with said sliding gear, a governor operated by said long faced gear, and
